design crowd Poor quality, worthless guarantee Internet

Purchased a "bundled" set of services consisting of website design, logo and business card for about $500, taking confidence in their money back guarantee which says, in essence, if you don't like it they will refund your payment (less their fees), which seems like they may be putting all risk on to their subcontractors.  If so, that is a rather revealing situation about the company.

Quality delivered was mediocre - about the quality of a high-schooler - and when my wordpress developer tried he found it unimplementable.  When I requested refund I got deferals and shifting answers.  Worse, I discovered they also delivered designs for the additional items without my approval and charged my account for those as well.  

I complained to the company repeatedly and they have offered every excuse in their clearly large inventory of them.  I hope that my $500 mistake is a learning experience for people considering using them...
